With careful design of micro-alloying composition, heat treatments as well as microstructure, this project will develop the next generation of austenitic stainless steels that will be able to operate at high temperatures above 850 degrees Celsius for future power systems.

Project Benefits

This project will develop synergistic computational and microstructural design of next-generation high-temperature austenitic steel. Next-generation high-temperature austenitic stainless steels are suitable for use in the ultra-supercritical temperature and pressure ranges. As well, synergistic use of computational and microstructure design methods can potentially be applied to other alloy design problems. Overall, improvement to high-temperature advanced-materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to improvements in efficiency and operational flexibility, and resulting in lower operating costs.
